She is an elected fellow of American Gastroenterological Association (AGA) and American Physiological Society (APS). She is Chair for the AGA microbiome section. Her research interests are host-microbiome interactions in inflammation and cancer. Her key achievements include 1) characterization of vitamin D receptor regulation of gut microbiome in intestinal homeostasis, inflammation and cancer, 2) identification of dysbiosis and intestinal dysfunction in Amyotrophic lateral sclerosis (ALS), 3) characterization of bacteria in regulating intestinal stem cells and leading to cancer, and 4) identification and characterization of the Salmonella protein AvrA in host-bacterial interactions. Dr. Sun has published over 180 scientific articles in peer-reviewed journals, including Gut, Gastroenterolog, Cell Stem Cells, Nature Genetics, JBC, Autophagy, American Journal of Pathology, & American Journal of Physiology-GI.  She is the leading editor of three books, including a recent Nature/Spring book entitled “Mechanisms underlying host-microbiome interactions in pathophysiology of human diseases.”  This book has shown a novel theme and multiple disciplinary topics of microbiome research for a broad audience. She is the author of Nature/Spring book “Statistical Analysis of Microbiome Data with R. This timely book addresses the statistical modelling and analysis of microbiome data using cutting-edge R software. She serves on the editorial board of more than 10 peer-reviewed international scientific journals. She services study sections for the NIH, American Cancer Society, and other national and international research foundations. She has been invited to chair meetings on microbiome, be a keynote speaker, and to write reviews, editorials, and comments on microbiome in human diseases published for peer-reviewed journals. She is actively involved in advocating microbiome research at the international, national, and institutional levels. Her research is supported by the NIH, DOD, VA, and other research awards.
